Upgrade Notes

Note: If your upgrade path skips versions of Nessus Agent, Tenable recommends reviewing the release notes for all skipped versions. You may need to update your configurations because of features and functionality added in skipped versions.

Caution: Nessus Agent version 7.1.1 might enter a state where it is unable to upgrade to Nessus Agent 7.1.2.

Upgrade options and instructions for Nessus Agents are available in the Nessus Agent 7.1.2 User Guide.

A 7.1.1 Nessus Agent might enter a state where it's prevented from applying a core update from 7.1.1 to a newer version, but still continue to receive plugin updates and run scans. The issue occurs when a plugin update (full or differential) and a core update are both available. The issue impacts any 7.1.1 agent that is managed by Nessus Manager and configured to automatically receive core and plugin updates. Agents managed by are not expected to experience the issue.

Agents will continue to receive plugins and run scans while in this state. The following options can be utilized to mitigate the issue and provide a way to upgrade impacted agents being managed by Nessus Manager.

  • Nessus Manager Upgrade - Upgrade your Nessus Manager installation to a newer version. Nessus Manager 8.0.1 includes logic that will prevent the issue and allow 7.1.1 agents to upgrade. Alternatively, you can upgrade to Nessus Manager 7.2.2 which is targeted for release on November, 15th 2018.

  • Manually upgrade the Nessus Agent on each asset.

If the two options above aren't feasible, you can recover from the loop with this workaround:

  • Restart the agent or the asset that contains the agent. Upon restart, the agent will check-in, process the core update to 7.1.2, and resume as normal.

Tip: You can examine a Nessus Agent's backend.log file to determine if a Nessus Agent is in a restart loop. An example log that illustrates the issue is available here.

Additionally, the 7.1.2 EA version should be uninstalled prior to deploying the 7.1.2 GA version.
